A10E/A28E/A28F Configuration Guide
Alpha-A28E(config-
port)#no oam remote-
loopback
(Optional) disable remote loopback. After
detection, disable remote loopback immediately.
You can discover network faults in time by periodically detecting loopbacks. By
detecting loopbacks in segments, you can locate exact areas where faults occur and
you can troubleshoot these faults.
When a link is in loopback status, the A10E/A28E detects all packets but OAM
packets received by the link. Therefore, disable this function immediately when no
detection is needed.
(Optional) configuring peer OAM event alarm
Enter global configuration mode.
Alpha-
A28E(config)#interf
ace port
port-id
Enter physical layer interface configuration mode.
Alpha-A28E(config-
port)#oam peer
event trap enable
Enable peer OAM event trap and then link
monitoring event can be reported to NMS center in
time. By default, device does not report trap to NMS
center through SNMP TRAP when receiving peer
link monitoring event.
(Optional) viewing current variable information about the peer device
Alpha-A28E#show oam peer
[ link-statistic | oam-info ]
[ port-list
port-list
]
Get OAM information or variable values
about the peer device.
By getting the current variable of the peer, you can get status of current link.
IEEE802.3 Clause 30 defines and explains supported variable and its denotation
gotten by OAM in details. The variable takes Object as the maximum unit. Each
object contains Package and Attribute. A package contains several attributes.
Attribute is the minimum unit of a variable. When getting an OAM variable, it defines
object, package, branch and leaf description of attributes by Clause 30 to describe
requesting object, and the branch and leaf are followed by variable to denote object
responds variable request. The A10E/A28E supports getting OAM information and
interface statistics.
Peer variable cannot be gotten until EFM is connected.
